Benefits of technology
This approach significantly shortens the time from radiation emission to displaying the combined image, enabling quicker decision-making and reducing patient waiting times by allowing for prompt evaluation and processing of radiographic images.
Problems solved by technology
When a subject is captured by using a radiographic image capturing device (Flat Panel Detector) which has a plurality of two-dimensionally arranged (in a matrix) radiation detectors generating electrical charges according to doses of emitted radiation, a capturing site cannot be fit in a size of a single radiographic image capturing device in some cases if the capturing site has a broad capturing area such as a full spine or a full leg of a patient.

[Modification Example]
[0134]The above embodiment has been described by assuming that the thinned data Dpre is transferred from the plurality of radiographic image capturing devices P1 to P3 (see FIG. 1) in one-shot long image capturing at the time of transferring the thinned data Dpre (Dpre_raw, Dpre_cor) to the image generator C from the radiographic image capturing devices P. The description also assumed that the thinned data Dpre is transferred from the radiographic image capturing device P as for the signal values D for each emission obtained by emitting radiation a plurality of times while moving the radiographic image capturing device P (see FIG. 14) by the moving type long image capturing.
[0135]However, in a case of one-shot long image capturing, for example, the thinned data Dpre may be transferred to the image generator C from any radiographic image capturing device P among the plurality of radiographic image capturing devices P1 to P3, and real signal values D* regarding t...

Provided is a flat panel detection system which is capable of appropriately shortening the time from irradiation with radiation for long length imaging to the display of a stitched image as well as the time taken for photography. Provided is a flat panel detection system 50, comprising: flat panel detectors P1-P3 which respectively read out, from a plurality of radiation detection elements 7, signal values D based on dosages of irradiated radiation; a display unit Ca; and an image generating unit C, 22 which generates a stitched image p. Before generating the stitched image p for output, the image generating unit C, 22 generates stitched images for verification ppre_raw, ppre_cor, by substituting an abbreviated process for any of the processes of a) generating radiological images p1-p3, b) image processing upon the radiological images p1-p3, or c) generating the stitched image p for output, and carrying out said process, and causes the display unit Ca to display the generated stitched images for verification ppre_raw, ppre_cor.
